Ulmus laciniata

(Trautv.) Mayr

Ulmaceae

This species represents an East Asian race replacing the European Ulmus glabra Huds., after a considerable geographical gap. Features characteristic of Ulmus laciniata may often be observed in Ural representatives of Ulmus glabra[

Comprehensive listing of species and how to grow them. Somewhat outdated, it has been replaced in 1992 by a new dictionary (see [200]).

This species is resistant to 'Dutch elm disease', a disease that has destroyed the greater part of all the native elm trees growing in countries such as Britain and the USA. The disease is spread by means of beetles. There is no effective cure (1992) for the problem, but most E. Asian, though not Himalayan, species are resistant (though not immune) to the disease so the potential exists to use these resistant species to develop new resistant hybrids with the native species[

Excellent and very comprehensive, though it contains a number of silly mistakes. Readable yet also very detailed.

]. The seed can also be harvested 'green' (when it has fully developed but before it dries on the tree) and sown immediately in a cold frame. It should germinate very quickly and will produce a larger plant by the end of the growing season[

Does not deal with many species but it is very comprehensive on those that it does cover. Not for casual reading.

]. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Plants should not be allowed to grow for more than two years in a nursery bed since they form a tap root and will then move badly.
